Manufacturers of Cooling Towers & Systems by Delta Cooling Towers, Inc.


MS-round series is a circular counter flow cooling tower which adopts a highly efficient rotating sprinkler head system to induce self rotation in distributing hot water across the fillings. The Fiberglass-Reinforced Polyester (F.R.P.) casing is round shaped thus eliminating special positioning requirements and is not affected by prevailing wind directions. It further allows quick and easy installation due to light-weight and compactness. MS-round is the most conventional, economical, and practical cooling towers with sizes ranging from 5 tons to 1500 tons. The MS-round standard series is suitable for general HVAC applications and various manufacturing process cooling. MS-U-round type features an upper fan stack and splash mat for running at lower fan speed based on the feature of fan blade. MS-U-round series has lower noise level than the standard MS-round model by 7~10 dB. 


Product Features

Casing, Water Basin, Water Sump

The Fiberglass Reinforced Polyester (F.R.P.) cooling tower casing, water basin, and water sump have been designed for durability. F.R.P. features good structure stress, non-chap, non-crack, non-aging, firmness and long service life. 

Fan Blade

Aero-dynamically designed propeller fans operated at low speed are used to save on power consumption and to ensure quiet operation. Models below MS-80 are made of special reinforced plastic fans. Model MS-100T upwards are made of aluminium alloy.

Water Distribution

A highly efficient self-rotating sprinkler head system made of reinforced plastic is used for the smaller range of towers. From MS-100T models upwards the sprinkler head is made of aluminum alloy. Spinkler pipes and stand pipes are of PVC plastic tubes featuring low water pressure, even water distribution, lower water consumption and maximum heat exchange efficiency. 


The embossed filling is made of PVC sheet that is processed by surface treatment of wrinkled and corrugated pattern. The filling is glued together to extend the retention time of flowing water and enable adequate surface in contact with the ambient air to increase heat exchange efficiency. PVC filling is suitable for operation with inlet water temperature up to 50°C. Additional filling options offered include CPVC and PP material for inlet water temperatures above 50°C. 

Inlet Louver

P.V.C. plastic mesh to prevent objects entering the water basin.
